Specification of Letters Patent. Patent d J 29 1920 Application filedOctober 16, 1918. Serial No. 258,367.

chanical means which control the movement of the sections of the bandforming the pictu res.

iVith the above and other objects in, view, the nature of which willmore fully appear as the description proceeds, the invention consists inthe novel construction, combina tion and arrangement of parts as hereinfully described, illustrated and claimed.

, 1n the accompanying drawings, forming plan; 7

Fig. 4 is a diagrammatic view showing a modification of the apparatushaving one exhibiting face; I

Fig. is a modified arrangement-for im parting to the band an increasingand decreasing velocity; s

Fig. 6 is a diagrammatic side elevation of the mechanism shown in Fig.5.

Referring to the drawings, 10 is an open framework formed of suitablematerial, which has on its opposite faces a plurality of band supports.11 disposed in a vertical row. Each support is rigidly secured to theframe with suflicient clearance between the from which the band is fed.A similar bearing 12 is provided on braces 14 of the frame to receiveanother roller 13 for similar purposes. A band 15 is threadedsuccessively from a support on one face to thosupport on the other faceuntil the other roll 13 is reached. lirconsequeiice, the illustratedband is zigzagged between the supports of the band onthe two faces ofthe frame.

Motion is imparted to the band 15 by endless belts 16 which mayfrictionally engage the band on the supports 11, or perforations may beprovided in the band and teeth 17 on the belt. The belts are supportedby rollers 18 which are mounted on tension arms 19 secured to the frame10. The arms are so set that the belt portion nearer to the supports isdrawn against said supports. The lower parts of, the belts are engagedby driving pulleys or sprockets 20 which are revolubly mounted-offcenter on plates 21,

the plates being coupled to driving shafts 22 with which therefore themembers 20 are eccentric. To prevent the belt portion in proximity tothe band from swaying to and from the band as the driving pulley movesin its eccentric path guiding rollers 23 are provided below the lowestband support The two driving shafts 22 are coupled. to a shaft 24 bybevel gears 25. driven from a suitable motor 26. ing conical pulleys 27and 28 are mounted to revolve on one of the shafts 22, the two pulleysbeing united to revolve together. The pulleys have a clutch extension 29with which a clutch member 30 maybe engaged and which is constrained torevolve with the shaft 22 whereby the pulleys are coupled to the shafton which they are mounted. Each pulley is provided with a belt 31 whichengages a corresponding cone pulley 32 and respectively, the two pulleysbeing mounted on independent shafts 34, the pulley 32 converging in adirection opposite to the pulley 27 and the pulley 33, to that of 28.

Each belt is engaged by a corresponding fork '35, the two forks beingunited by a sleeve 36 which has athreaded engagement with a screw 37 towhich motion is imparted by a belt 38 engaging a suitable pulley 89 onthe extension 29 of the pulleys 27 and 28. In consequence the two beltsare shifted simultaneously on theconical pulleys and different speedswill be'imparted to the two shafts 34. These shafts carry pulleys 40 Theshaft 24 is Converg which are coupled to the rolls 13 and whereby saidrolls are driven at different speeds .aceording to the quantity of bandwound thereon.

The other shaft 22 carries a worm 41 with which a worm gear 42 meshes.The gear 42 has a plurality of apertures 43 at the mar gin adapted to beengaged by removable pins 44. The arm 45 lies in the path of the pins,the arm being connected with a reversing mechanism 46 which controls thedirection of rotation of the motor 26 and, therefore the movement of thebands in either direction. By varying the angular distance between thepins 44 different lengths of bands may be used in the machine. Suitableyielding means 47 are provided for retaining the arm 45 in displacedposition until again moved by a pin.

In Fig. 4 the band is zigzagged over pulleys 48 located in the rear, andalso over pulleys 49 positioned between the band supports and thepulleys 48. Said pulleys 49 are mounted in a suitable frame 50 which canbe adjusted vertically and, therefore,

take up any amount of lag necessary to properly adjust the sections of aband on the supports 11. The band, if desired, may be made endless, asindicated in dotted line in said figure. Suitable guiding pulleys wouldhave to be provided for the purpose.

\Vhen the picture formed by the sections of the band is to remainimmovable for a comparatively long period of time, the movement of theband is accomplished by means of a rigid frame 51 having teeth forengaging the perforations in the band. The frame has also horizontalslots 52 at the top and bottom engaged by crank pins 5-3 to which motionis imparted from a driving shaft Springs 55 draw the frame toward theband against the resistance of which the crank pins work when they drawthe frame away from the band to move it without displacing the band.

In cases where the eccentric driving pulleys 20 cannot be used, avarying velocity. can be imparted directly to the shafts 22, by whichthe bolts 16 are driven, in the following manner (see Figs. 5 and 6). Onthe driving shafts 22 a pulley 56 is provided. Motion is imparted tosaid pulley and therefore to the shaft 22 by a pulley 57 constrained torevolve with a plate 58 which carries a crank pin 59. An elongated slot60 of a crank 61 is engaged by the pin 59. The crank is constrained torevolve with a shaft 62 which is driven by the motor. The bearing 63 forthe shaft 62 may be adjusted so that the distance between the axes ofthe shaft 62 and the plate 58 may be adjusted and, therefore, the speedof the shaft 22' varied.

To render the inanimate signs more realistic, I provide a talkingmachine the disk carrier 64 of which is driven from the shaft 24 bysuitable bevel gears 65. The sound box 66 has securing means 67 forpinching or clamping an inextensible flexible member 68 to the soundbox, one end of which is con nected to the sleeve 36 of the shifter ofthe differential mechanism. The other end of the flexible member 68 isconnected by a spring 69 to the arm support 70 of the phonograph,guiding pulleys 71 being provided for the flexible member to maintainthe proper relation with the sound box. The sound box 66 is alsoconnected by an inextensible flexible member 72 to an arm 73.

A cam 74 is )rovided on the shaft which extends from tie arm 45 to thereversing mechanism 46, said cam being positioned in proximity to thearm 73 over which the flexible member 72 passes. The engagement of saidcam with the arm will raise or lower the sound box. To the arm support70 two rigid arms 75 are secured which are adapted to be disposed toeach side of the sound arm.

Each of the arms 75 carries an inclined plane 76. The inclined plane 76near to the center of the disk is adapted to engage the needle of asound box and raise it from the sound box as it is advanced by theflexible member 68. The return to the margin of the disk is accomplishedby the spring 69 which has been tensioned by the flexible member 68.WVhen the sound box is returned by the spring 69 it is raised from thedisk by the cam 74, and when it reaches the incline 76 it will beengaged by said incline; and as the movement is reversed, the cam 74will slacken the flexible member 72. The movement of the sound box willbe taken up by the flexible member 68, and the incline 76 will allow theneedle to come into engagement with the disk on the carrier 64. Theinclines 76 are adjustable on the arms so that the point of engagementof the needle with the disk and the disengagement of the needle from thedisk may be controlled in accordance with the length of the band used.
